Abstract

A rectangular waveform voltage is applied between electrodes for welding by using a variable voltage-variable frequency type inverter as the power source for welding whereby the local short-circuit between workpieces can be immediately changed to the flash whereby the fine flash can be continuously generated to remarkably improve the quality of the welded part, and the voltage control can be attained without changing the voltage waveform.
